In contrast to those highly graphical design tools, harness professionals can use EB Cable for purely digital structural manipulation. The data structures created by assembly rules are just another representation of the data and are therefore usually displayed automatically. Regardless of the view window, changes are made once and automatically saved to a unique data source. In addition, EB Cable’s database can store a variety of templates, from simple to highly complex, reusable and easily customizable. For example, the ECU already “knows” which connectors are needed for its pins, and the system “knows” which signal connections to implement. Devices in each project can be extended with any number of properties, all of which can be edited.
